Speech Title: Synthesis of Porous Metal Oxide Semiconductor Nanomaterials and Their Gas Sensing Performances
Abstract: High sensitivity, rapid response, low power consumption, and excellent stability are significant for practical applications of gas sensors. As the core component of gas sensors, sensitive materials require porous structures, which facilitates gas diffusion and adsorption as well as provides abundant active sites.This research focuses on improving gas-sensing capabilities by designing and fabricating various porous metal oxide semiconductors and next-generation porous carbon-based gas-sensitive materials. Through systematic investigations into the intrinsic relationships between material composition, microstructure, heterojunction types, and sensing performance, we have achieved highly sensitive, fast-response, low-power, and stable detection of target gases.
Keywords: Porous structure, enhanced gas response value, fast response, low working temperature,metal oxide, graphydine
